U.S. Representative Andy Biggs won the Republican nomination for Arizona governor in the July 21, 2026, primary. He defeated three Republican opponents, including U.S. Representative David Schweikert, who was seen as the more moderate candidate. Biggs had the endorsement of Donald Trump. He will now face Democratic Governor Katie Hobbs in the November 3 general election.

Biggs refused to certify the 2020 presidential election results, citing Trump's unverified claims that the election was stolen. In the 2022 governor's race, Hobbs narrowly defeated Republican Kari Lake. Trump won Arizona in the 2024 presidential election, keeping the state in swing-state territory, meaning both parties have a real shot at winning there.

The Cook Political Report, a group that rates how competitive political races are, had called the governor's race a toss-up before the primary. After the primary results, Cook changed its rating to a slight Democratic advantage.

Trump's influence showed up in other races too. Alexander Kolodin won the Republican nomination for secretary of state, the office that runs elections in Arizona. Kolodin, a lawyer, took part in lawsuits challenging the 2020 election results. Adrian Fontes, a Democrat, currently holds the office.

In Arizona's 1st Congressional District, former NFL kicker Jay Feely, endorsed by Trump, won the Republican nomination over Joseph Chaplik, a former state lawmaker who was part of a conservative group called the Freedom Caucus.

The primary drew national attention because of what it showed about voters in a key swing state. Two of the 18 congressional districts rated as true toss-ups nationally are in Arizona. Reuters reported on July 21 that Democrats were hoping Republicans would nominate far-right candidates in Arizona, betting that those candidates would be harder to elect in November.

NPR published a report on the results on July 22 that included an Associated Press photograph by Ross D. Franklin showing a poll worker helping an Arizona voter at a Phoenix polling location. PBS NewsHour carried live results coverage of the Arizona primaries.

The general election is scheduled for November 3, 2026, with early voting starting October 7. Maricopa and Pima Counties must mail sample ballots at least eleven days before a general election. The Arizona Secretary of State's office posts unofficial results on election night, and full results are available through the state's election website.

The broader context here is that Arizona Republicans have now nominated candidates for two of the state's top three offices — governor and secretary of state — who both challenged or objected to the 2020 election results. Trump won Arizona in 2024 by a narrow margin, which keeps the state competitive. The question for November is whether the party's primary voters picked nominees who can win enough moderate voters to prevail statewide, or whether the Democrats' bet that they will face opponents too extreme for most voters will pay off. The Cook Political Report's shift toward Democrats after the primary suggests at least one nonpartisan group sees an opening for Hobbs. But Trump's 2024 Arizona win and the state's toss-up House races show the partisan divide remains close enough that the candidates themselves and how many people turn out to vote will likely decide the outcome.
